Overview
Record a web task flow and convert it into an original KLM breakdown.
Keystroke-Level Model Analyzer helps you compare web task flows quickly by turning interaction traces into auditable Keystroke-Level Model (KLM) estimates. Inspired by Card, Moran, and Newell's The Psychology of Human-Computer Interaction and Jef Raskin's The Humane Interface, the extension records a web task flow, converts the interaction trace into K, P, M, H, and R operators, and reviews the estimated expert execution cost with a step-by-step breakdown. Use it to compare prototype versions, validate design ideas, and identify the highest-cost step in a flow. Features: - Record web task flows on prototypes and real web apps - Auto-capture clicks, typing counts, scroll bursts, and response candidates - Convert modern interactions into original KLM operators - Review KLM estimate, operator counts, primary cost driver, and audit trace - Edit step classification before finalizing the estimate - Save recent measurements locally in your browser Keystroke-Level Model Analyzer stores measurement data locally and does not store typed text values.
